Thank you for your answer but I wanted to know the update cycle of the 1.2 beta version. 2-4 weeks appear to be a bit long for that, especially as there could be breaking bugs in there. If that's the case I don't think testing it would be really feasible.

Sorry I didn't understand your question. I said that whenever the v1.2 becomes stable the update cycle will be the same as in v1.1 (2-4 weeks). But in the beta phase, we will update more frequently. At least, right now, that we are providing only x86 binaries. In fact, we are preparing a new version for today.
